Cao Yu

Cao Yu (?-?) was the King of Yan and the son of Cao Pi. When Cao Rui was sick in bed, he was made Grand General and ordered to advise the newly ascended Cao Fang. He firmly refused due to the heavy responsibility. Historically, he was actually Cao Cao's son. His wife was the daughter of Zhang Lu and their son Cao Huan was the last Wei emperor.
